Abstract

PURPOSE:To easily obtain correspondence by moving a place where device dependence information on a personal computer side is held from a host side to the personal computer side. CONSTITUTION:A device dependence information storage file 3 is generated on the personal computer by drawing interaction through a device dependence information storage file generation part 4. A personal-computer side data transfer program 5 inputs the device dependence information such as the names of an input/output device and a data file from the file 3 through a device dependence information storage file access part 2 and performs data transfer without any drawing interactive processing. Therefore, even if the device dependence information increases in the number of kinds, that can be handled only by modifying the program of the personal computer side without the interaction of the host-computer side program.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to means for managing device-dependent information when a program for transferring data between a host computer and a personal computer carries out data transfer processing.

[0002]

2. Description of the Related Art Conventionally, when a distributed program for data transfer between a host computer and a personal computer performs data transfer processing without going through screen interaction processing,
It is necessary to specify the input / output file name and the input / output device on the host computer side. In this case, the program on the host side that inputs the specified value corresponds to the input value format of the file name and the device specified value on the personal computer side. Need to be.

[0003]

In such a conventional example, since it is necessary for the host computer side to be able to specify the device-dependent information of various types of personal computers, the number of types of personal computers connected to the network is required. However, there is a drawback that the device-dependent information needs to be specified at the time of execution, the specification on the host computer becomes complicated, and an error is likely to occur. Further, when a new type of device comes out, it is necessary to support a program on the host computer side in order to support the device, and there is a disadvantage that it cannot be used in a system that does not perform screen interaction unless it supports it.

The present invention eliminates such drawbacks, and an object of the present invention is to provide a device-dependent information management device having means for easily managing the device-dependent information even if it increases.

[0005]

The present invention executes a program for controlling data transfer processing between a host computer and one of a plurality of personal computers connected to the host computer, and is used at that time. In a device-dependent information management device equipped with a data transfer processing unit that specifies device-dependent information that does not involve screen interaction processing, a record that includes the device and file name for input and output related to the device-dependent information is transferred to the transfer data name. The device-dependent information storage file creation unit that creates the device-dependent information storage file to be stored in the personal computer, and the record of the device-dependent information storage file at the time of data transfer processing is searched for by the transfer data name that has already been transferred. A device-dependent information storage file that gives the retrieved record to the data transfer processing unit. Characterized by comprising an access portion.

[0006]

The device-dependent information storage file is created on the personal computer through screen interaction by the device-dependent information storage file creation unit. The personal computer side data transfer program fetches device-dependent information such as input / output devices and data file names from the device-dependent information storage file through the device-dependent information storage file access unit,
Data transfer processing is performed without going through screen interaction processing.

FIG. 3 is a program configuration diagram of a data transfer program that implements the present invention. The data transfer program is composed of a host computer side data transfer program 5 and a personal computer side data transfer program 6, and both cooperate to perform data transfer processing. The host computer side data transfer program 5 reads data from the data file of the host computer and transfers the data to the personal computer side data transfer program 6 on the personal computer connected to the network. Further, the personal computer side data transfer program 6 reads the data from the personal computer side data file and transfers the data to the host computer side data transfer program 5 on the host computer connected to the network. At this time, when the data is output to the data file, the data is converted into the host computer format or the personal computer format and is output.

FIG. 3 is an operating environment diagram of the data transfer program. The host computer 7 can be connected to a personal computer 8 or a personal computer 9 connected to the network. Here, since the device-dependent information is different between the personal computer 8 and the personal computer 9 when data transfer is performed, data transfer cannot be performed with the same device-dependent information. As a method of executing the data transfer program, there are a method of specifying a file name and device-dependent information to be interactively transferred as an input value from the screen, and a method of executing without interactive input from the screen.

Next, the input method and management method of the device-dependent information on the personal computer side when executing without interactive input from the screen will be described.

The record is composed of a transfer data name R1 used to retrieve information of transfer data, input / output device information R2, input / output file name information R3, data conversion information R4, and additional information R5. . There are as many records as the transfer data name R1. The transfer data name R1 corresponds to the name of the transfer data sent by the host computer side data transfer program, and is the name of the transfer data sent by this host computer side data transfer program. The transfer data name R1 item in the record in the file 3 is searched to extract the device-dependent information, and
